I have 285/70 Nittos on the stock Rubicon wheels (no spacers) and have no clearance problems, front or back, including full lock turn at the sway bars.
We had a big discussion on this a while back and one of the participants (stock wheels with 285/70 Duratracks) did have a slight sway bar rub on one side (but not the other) at full lock. Im my opinion that's a track bar adjustment issue.
If you go with aftermarket wheels with the standard 4.5" back space, then you move the wheels outboard by 2 inches, and while increasing your inside clearances, you place the tire tread under the fender lip, reducing your clearance there.
I had that setup on a previous JK and I did have very slight contact with the lip under a full "to the stops" compression in the rear. Very slight, but enough to know I did it. That could be eliminated with no more than a half inch spacer on the springs.
So, the answer is... yes you should be able to use those tires without any problems that can't be very easily fixed.
